This pin replaces the John Deere clutch linkage pin. Original John Deere part number D1994R(large pin) or B178R(small pin). The only difference is that this pin is oversized to allow you to "Tighten up" that worn and sloppy linkage. This pin's diameter is set to match a 9/16 drill(for the large pin kit)or 1/2" drill(for small pin kit) IF reaming of the original linkage is required. Original drawing may be found in your copy of your John Deere Tractor Parts Catalog. Tractors use two pins. This kit is supplied with both pins so that you may tighten the entire linkage system. Used on John Deere A,D,R,G,50,60,70,520-730(Large Pin Kit) & B, H(Small Pin Kit) Tractors.
*The part B178R fits all "B" and "H" Tractors please order correct pin kit for your tractor.
